5G millimeter wave ultra-wideband dipole antenna unit and packaged antenna module

Abstract

The invention discloses a 5G millimeter wave ultra-wideband dipole antenna unit and a packaged antenna module. The 5G millimeter wave ultra-wideband dipole antenna unit comprises a first dielectric layer, a balun which is arranged on the top surface of the first dielectric layer, and a first metal layer which is arranged on the bottom surface of the first dielectric layer; the first metal layer comprises a ground layer, a gap and a dipole, the gap is arranged on the ground layer and is coupled with the balun, the dipole is connected with a first side edge of the ground layer and is coupled with the gap, and the first dielectric layer is provided with a first plated-through hole used for feeding the balun. The n257 (26.5 GHz to 29.5 GHz), the n260 (37 GHz to 40 GHz) and the n261 (27.5 GHz to 28.35 GHz) can be effectively covered, and the coverage frequency band is wide; the antenna is small in overall size, can be based on a PCB, is more convenient for subsequent integration with a chip, and is especially suitable for hand-held equipment of a 5G millimeter wave communication system; and the design difficulty, the test difficulty and the beam management complexity are effectively simplified.

Description

technical field [0001] The invention relates to the field of antenna technology, in particular to a 5G millimeter wave ultra-wideband dipole antenna unit and a packaged antenna module. Background technique [0002] As 5G is the research and development focus of the global industry, the development of 5G technology and the formulation of 5G standards have become the consensus of the industry. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU clarified three main application scenarios of 5G: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter wave are the main means to achieve 5G ultra-high ...

AI Technical Summary

Problems solved by technology

[0004] Conventional millimeter-wave broadband antennas are either large in size and not suitable for terminals, or have low gain, so it is necessary to improve the bandwidth and gain of PATCH antennas. Therefore, it is necessary to provide a packaged antenna module that covers a wide frequency band and occupies a small space
